Most certainly, HD and SD formats can and will co-exist. We are in the very early stages of HD broadcasting despite it being developed over the last two decades. Only now is it becoming commercially viable. The move towards HD is driven by costs: Consumers are unwilling to pay high premiums for HD and broadcasters will not commit to HD broadcasting until they can see a return on the investment. Producing HD material increases production costs several times over. Better sets, make up, lighting and equipment are all required to make the best of HD content. Studio equipment typically has a life of 10 years or more so we can expect standard definition studios to be around another ten years from now. Broadcasters will be reluctant to refit studios before they reach the end of their natural life, so SD production will also be with us for another decade. Many specialist and low budget channels have no budget and indeed, no requirement to move to HD. Those minor channels will be moving to HD only when HD equipment costs are in line with SD equipment. That's a few years away. Although HD in the home is becoming more common, by no means every home will have HD in the foreseeable future. SD broadcasts will be required for SD homes for many years to come. In the UK, color television was rolled out by the early 1970s. It took 40 years before the old monochrome transmitters were finally turned off after that roll out. HD signals take 5 times the bandwidth of SD. As broadcasters struggle to find space on cable and on the transmission spectrum for new HD channels, SD will still be used to allow the wide range of channels that we expect. Finally, archived material is SD. It will always be SD. Although one day, it will be upconverted to HD for broadcast, this will not improve the quality of the material and there is no justification for HD broadcasts when a channel relies heavily on older archived material. All HD televsions are capable of displaying SD signals and there is no pressure on broadcasters to move to HD just for compatibility reasons. As a personal view, I do not believe that SD will become scarce for another decade. Perhaps, in 15 years, we will have moved almost fully to HD. As I write this in 2009, I will review this answer in 2019 and 2024 to see how close my prediction is to the reality of those future times.
Yes.
The benefits of High Definition (HD) video are that it primarily has a better picture than a Standard Definition video would. Therefore, you are likely to see more detail with a high definition video than you would if you were to watch it in the standard version.
YES
There is no standard definition across countries.
Yes the Playstation 3 console supports video output in standard as well as high definition.
The picture is much better, you can see the news readers eye lashes.
only with a converter box, but then it becomes just standard definition
High definition television is better than the standard picture because it offers a more clear and sharper image in the picture. High definition also has a much higher screen resolution.

You can connect your standard definition TV to your satellite receiver in a couple of ways. First, if your TV has composite video/audio inputs (yellow, red, and white RCA jacks), you can connect to these inputs using the composite video outputs of the satellite receiver. Another alternative is to use the standard coaxial cable output from your satellite receiver to connect to the 75ohm antenna input on your TV. *Note: Neither of these connections will display high definition programming on your standard definition TV. The TV is only capable of standard definition, so you will see a clear picture, but it won't be true high definition, regardless of the input signal's definition.
All VCR's work with High Definition tv's,but you'll usually only be able to play back and record in standard definition or Super VHS.
DirectTV is a satellite broadcast platform delivering both standard and high definition television. As all high definition televisions will handle both SD and HD content, DirecTV is fully compatible.
